LAMP.

SPECIFICATION forming part of Letters Patent No. 458,509, dated August 25, 1891.

Application filed October 9, 1890.

To all whom it may concern;

Be it known that I, CHARLES H. VAN HISE,

A of New York, in the county and State of New York, have invented a new and useful Improvement in Lamps, of which the following is a full, clear, and exact description.

This invention relates to oil-burning lamps, and has for its objects to produce a lamp adapted for the illumination of streets or other exterior service and containing means for self-extinguishment at any desired period of time, the devices for predetermined extinguishment being also applicable to fixed or portable lamps that may be employed for interior use. 7

' To these ends my invention consists in the construction and combination of parts, as is hereinafter described, and indicated in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

automatic extinguishment of the lamp. Fig. 9 is a side elevation of the same, showing the extinguishing device in the act of automatically extinguishing the lamp. Fig. 10 is a sectional plan view taken on the line 10 10 in Fig. 3, and Fig. llis a detail partly sectionalview of a portion of the Wick-extinguishing device.

The oil-receptacle of the lamp, when de signed for outdoor service, is preferably made in three sections or chambers A B C, which are of cylindrical or other suitable form. As shown in Fig. 3, these chambers are secured together laterally in the same vertical plane by tubular braces a a, which are of the same length, and by their attachment to the sides of the chambers hold the side chambers A and C properly removed from the central chamber.

Upon the upper portions of the oil-holding chambers A (J conical top pieces A C'are respectively secured, forming portions of said chambers, and upon the apex of each top the tubular columns A G are afiixed, which latter are of equal height and sustain a light-re- The central chamber B is comprised of two cylindrical portions, which are concentrically arranged, and the inner portion B, that is made annular by the introduction of a central cylindrical air-conduit B in its bottom wall a is retained in position within the outer shell B by the oil-conveying branch pipes a that intersect the oilchamber 13 and chambers A C, said branch pipesbeingpreferablylocated within the tubular braces a, that are placed near the bottom of said chambers, as shown in Fig.3. The space between the outer shell B and concentric inner oil-chamber B is suliicient for the free passage of air upwardly in the annular conduit 1) thus produced, the use of which will hereinafter appear.

The upper terminal edges of the walls forming the shell B, oil-chamber B, and central air-tube B are located nearly in the same horizontal plane with the bases of the conical tops A C of the chambersA and C, and are turned inward slightly to enable the ready attachment thereto of mating tubular extensions 1 2 3, which are of such a relative size, diametrically considered, that the extensions will closely fit upon the respective walls they are adapted to engage when said parts are to be connected, and thus form removable portions of the same. (See Fig. 3.) The outer top piece 1, which has a sliding engagement with and is seated upon the upper end portion of the outer shell B, is contracted near its upper end portion, and at a proper point thereon a gallery E is formed on or secured to the outer surface for support of a lamp globe or chimney F, made of glass. (Shown broken away and in position on the gallery; see Fig. 3.) Above the lower edge of the globe F the upper portion of the tubular piece 1 is flared slightly, and within it a cylindrical perforated wall I) is secured by its upper edge nearly opposite the gallery E, the lower edge of said wall b resting upon the incurved upper portion of the top piece 2, whereby an air-restraining vertical partition is produced that controls the upward flow of air through the annular channel or passage 1).

A wick-tube of nearly continuous cylindrical form is produced by the wall 3 and larger tubular piece 0, that is oppositely severed, the two equal sections thus produced being attached to the wall 3 by end walls 0, thus producing two wick-passages of the same dimensions, wherein two flat wicks, when introduced, form a nearly continuous cylindrical wick, which is vertically adjusted by the usual wheels 0 on the transverse shaft 0 Within the upper portion of the tubular wall 3, that is an extension of the central air-tube B a short cylindrical thimble d, that neatly fits the tube, is slid therein, the relative proportion in size being such that the thiinble may be freely reciprocated in the piece it engages. Upon the exterior of the wick-tube, opposite the thimble (Z, an enveloping-cylindrical sleeve (2 is connected to the thimble by the webs 6, (see Fig. 6,) that are diametrically opposite each other and lie between the wick-tube sections, the lower edge of the sleeve resting normally upon the upper edge of the top piece 2 of the shell 13.

Within the upper portion 3 of theair-tube 15 a central guide-rod g is located, which is firmly supported in position by an engagement of its transverse foot-piece g with the inner surface of the piece 3 near its lower end, said foot-piece resting on the upper edge of the air-tube B when the parts are assembled, as shown in Fig. 3. \Vithin the thimble cl a foraminated shell 9 of cylindrical form, is inserted, which fits loosely the upper edge of said shell, engaging a deflector-plate of circular contour and such a relative diameter as will permit its edge portion to coincide with the circumference of the sleeve d when the plate and sleeve are brought together.

A filler-nozzle and screw-cap f is provided for the chamber A, and is locatedin the conical portion A, and the chambers A B O are furnished with depending flanges f f f which protect the bottoms of the oil-receptacles, a series of perforations being formed in the flange f on the shell B to admit air if the lamp is seated upon a solid base-plate or other similar support. Vt ithin the oilchamber 0 a hollow float H is introduced, which is filled with air, and thus adapted to rest partly submerged upon the surface of the oil in the chamber, the relative dimensions being such that the float will slide in the chamber. Upon the float II a central standard H is erected, which may be made cylindrical, but for convenience in manipulation is preferably given a square form in cross-section. At opposite points the conical wall 0 is slotted horizontally to permit the edge portion of a disk or thumb-plate H to project through said slots, which it loosely engages, so that a manipulation of the disk will effect a revoluble movement of the standard H, which passes loosely through a square aperture in the center of the thumbplate. (See Figs. 3 and 10.)

A depending hollow limb g is centrally secured to the lower surface of the deflectorplate 9 and at its lower end is pivoted to the forked limbs of a lever 2', that is loosely secured at its lower end to one end of a centrally-supported rocking bar 7;. The other end of said bar t" has a pivoted connection with the main limb of the bifurcated lever 2' the upper forked portions of which lever straddle the lever '7; and guide-rod g and are pivoted to the lower edge of the thimble (Z. The proportion of parts is such that when the rocking bar 2" is inclined in one direction the deflector-plate will be elevated and the joined thimble d and sleeve (1' moved in an opposite direction, so as to expose the upper ends of the wicks G, as shown in Fig. 4, an opposite inclination of the rocking bar throwing the concentric sleeve and thimble upwardly, so as to meet the descending deflectorplate 9 as represented in Fig. 5.

Upon the side or top portion 1 of the shell B adjacent to the chamberG a gravity-block I is held loosely in the parallel upright guides by its opposite edges, so that it may reciprocate vertically. The lower portion of the gravity-block I is transversely slotted near its center of width from the lower edge upwardly a proper distance, which slot 'm is loosely engaged by the end portion of a tripping-lever J', that is supported by the transverse shaft 02, which is journaled at its ends loosely in the wall of the conical top 0, as represented by dotted lines in Fig. 10. The vertical guides it are located at one side of a vertical plane which would pass through the axes of both chambers B O to enable the tripping-lever J to enter the conical top C and lie with its free end aligned with the plane of the axes of the chambers C and B. The tripping-lever is bent laterally at n and forwardly at 92 entering a slot of in the top piece O and projecting toward the upright standard H.

A series of evenly-spaced push-pins O are made to project from each face of the square standard H, the spaces between the pins on pins from contact with the plate. (See Fig. 10.)

- As will be seen in Figs. 3 and 10, the shaft 'n is located near the end 91 of the lever J,

and upon said shaft a latch-dog p is loosely clipped by its forked limbs, so that the free end portion of the dog which projects toward the standard H in the path of the push-pins .0 will be engaged by the lever end n and prevented from falling, being held extended thereby as a portion of the lever, while an upward movement will be permitted if the end of the dog that is in the path of the pins is pressed upon from below by an upward movement of the standard H and series of pins on it.

As represented in Fig. 11, the connection between the end of the tripping-lever J and the slotted portion of the gravity-block I is effected by a rocking bail I, which is loosely journaled where it is bent at its middle in the perforated body of the lever near the end 0' of said lever, the upwardly-extending limbs of the rocking bail havingtheir laterally-bent end portions 0" inserted in opposite perforations in the walls of the slot m, whereby the vertical vibration of the lever J is permitted and a guiding connection established between the end of the lever and the gravity-block I. Upon the side face of the gravity-block I a peculiarly-shaped locking-plate I is pivoted at one upper corner 5, which is nearest to the j axial plane of the oil-chambers B O, and directly below the pivot at s the side of the plate is cut away inwardly to a point 3 sufficiently removed from the pivot, and thence downwardly and outwardly to the corner 3 of the plate 1 directly below the corner 8.

Referring, again, to the rocking bar '6, it will be seen that said bar is secured at its center of length upon the end portion of a horizontal rock-shaft n, which latter projects through aligning perforations in the walls '1 2 3 of the movable tops on the shell 13, oilchamber B, and center tube 13 which afford a loose support for the shaft, as shownin Fig. 3. Upon the end of the rock-shaft a which is nearest to the gravity-block I a crank-arm u is secured, which projects at a right angle from the shaft toward the edge of the gravity-block and is of such a proportionate length that the free end of the crankarm, which is rounded on the edge, will be adapted to lie below thepivot s of the locking-plate I and nearly have contact with the curved edge of the plate at its portion 8', this position of parts being effected when the gravity-block I-is at its lowest point of adjustment, as shown in Fig. 7, the inner end of the latch-dog 19 being fully elevated and the extinguishing mechanism for the wicks G in open adjustment, which will permit the necessary combustion of oil for purposes of illumination.

In operation, the oil-chambers having been supplied with a proper quantity of oil of any suitable quality, the consequentelevation of the float H and standard H will cause the latter to move up into the column 0 as shown in Fig. 3. The spaced intervals between the four series of push-pins 0 being different, represent different periods of time which will elapse between the engagement of consecutive pins of a series with the free end of the latch-dog p as oil is gradually consumed at the point of ignition of the wicks G.

It is evident from the foregoing description that if the several parts of the burnermechanism and extinguishing device he in adjustment, as shown by full lines in Figs. 3 and 7, that the consumption of oil will cause the float H to gradually fall, which will rock the end 0" of the lever J upwardly, thus elevating the gravity-block I. WVhen the consumption of oil has progressed such a length of time as will lower the engaged push-pin O to a point of release, as shown by dotted lines in Fig. 3, the block I will then have been raised and the locking-plate I rocked on its pivot a sufficient distance to permit the crank-arm 'u, to release the plate and the corner 5 of the plate to swing above the arm at the same inat its end nearest the standard H.

In Fig. 8 the adjustment of parts represents the position of the gravity-block I and locking-plate I just before the rocking movement of the latter piece is fully effected, and in Fig. 9 the locking-plate is shown as having swung over the arm u and by the imposed weight of the gravity-block I, plate I, and long arm of the released tripping-lever J partly depressed the crank-arm, which when fully accomplished will throw the extinguishing mechanism into closed adjustment, as represented in Fig. 5.

The distance betweenthe pins 0 of one series'may represent an interval of, say, three hours burning before extinguishment of the light, another series may be for a period of five hours, another for seven hours, and the remaining series for ten or twelve hours, or any other preferred time-graduations may be represented on these pin-racks between the successive pins composing each one. Consequently it is only necessary to move the standard H so as to locate the proper series in the planeof the latch-dog p and adjacent to it, when the lighting of the lamp will be all that is necessary to cause its own extinguishment at the expiration of the interval of time represented by the space between the pins of the engaged series.

InFigs. 1 and2 the com pletelamp for outdoor illumination is shown mounted upon a post M or bracket-arm 0, there being a threestant that the lever J is completely depressed no V limbed bracket N provided, which is adapted to clasp the lower ends of the oil-chambersA B C and retain the lamp in avertical position on the post or bracket-arm.

As previously mentioned, the columns A (J are engaged at their upper ends with a lightreflector D, which is centrally apertured and provided with a vertically-movable smokeflue D, on the top of which the hood D is secured, the lower end of the flue beingmade to fit over the upper end portion of the globe F, so that protection is afforded to the flame of the lamp-burner and proper ventilation secured. The air-passages upon the inside and outside of the wicks G insure a full supply of oxygen to the ignited wicks, so that brilliant illumination will result if good oil is used in the lamp.

By a slight modification of form in the oil chambers and supports therefor the self-extinguishing devices may be applied to indoor uses for stationary, pendent, or portable lamps. Hence I do not limit the application of the improved automatic extinguishing device to the form of oil-chambers herein shown, claiming the right to vary therefrom Within the manifest spirit and scope of my invention.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1.
